Certified Flight Instructor - Flight Instructor Airplane Practice Exam

Which of the following is required by regulations regarding the use of oxygen systems in aircraft?

1. Oxygen systems must be serviced by a licensed technician

2. Only liquid oxygen should be used

3. Oxygen systems need to be inspected before each flight

4. Emergency oxygen must be available for all crew members

The correct answer is: Oxygen systems must be serviced by a licensed technician

The correct answer, indicating that oxygen systems must be serviced by a licensed technician, reflects the importance of proper maintenance and safety in aviation operations. Regulations dictate that oxygen systems must be maintained, tested, and repaired by qualified personnel to ensure they function correctly in the event of an emergency. This requirement helps to prevent malfunctions that could arise due to improper handling or servicing. Ensuring that a licensed technician works on oxygen systems is critical because these systems are essential for crew and passenger safety at higher altitudes, where the air pressure may not provide adequate oxygen levels. Proper servicing by trained professionals ensures that the systems are functioning appropriately and meet safety standards. While having emergency oxygen for all crew members is crucial, the regulations specifically emphasize the need for servicing and maintaining the systems by qualified individuals as a prerequisite for ensuring safety and compliance. Other options mention specific types of oxygen usage or inspection protocols, but they do not focus on the qualification and training necessary for equipment servicing, which is a cornerstone of aviation safety regulations.
